Frostgrave is a game of Wizards, battling through a ruined frozen city in search of magical artefacts. Amidst the frozen ruins of an ancient city, wizards battle in the hopes of discovering the treasures of a fallen empire. In this fantasy skirmish wargame, each player takes on the role of a wizard from one of ten schools of magic, and builds his band of followers.

In The Forgotten Pacts supplement for Frostgrave, players lead their warbands into the northern reaches of the city, exploring the ruined temples of the Frozen City to search for the lost secrets of evocation - the art of summoning demons. While the lure of such knowledge is great, few wizards have ventured into this region as it is overrun by barbaric northern tribesmen who have descended from the hills in their own search for treasure. Marking themselves with demonic sigils, many of these barbarians have aligned with ancient powers discovered amongst the temples.
